    Yeah, I'd say the epoxy is useless. Calling a mobile welder.

    A mechanic has a big mental tool bag of skills. You need to use AI to get a list of the possible methods. Problem is you haven't the muscle memory of any of these skills and you don't have the tools.


    Solutions:
    1. Electromagnetic induction heater: Magnetic Induction Heater Bolt Removal https://a.co/d/0ZqvJ1Y

    2. Weld a nut onto it and use that plus heat

    3. Use grinding wheel to grind bolt flat and used hi carbon steel bits purchase anywhere except harbor freight after using a center punch to drill into that bolt with left-handed drill bits and then an easy out

    4. Cut a piece of aluminum off and TIG weld in other piece of aluminum on drill it and start over
